M invention relates to mechanical refrigeration, and particularly to means for form- A ing, by the action of the refrigerating unit of ill tacle 11 and the strip 12, an

a domestic mechanical refrigeration up aratus, ice blocks of a size suitable for ta le use, and the principal object of my invention is to provide new and improved means of th s type. In the drawings aceompan mg this specification and formimg a part 0 this application I have shown, or purposes of illustration, several forms which my invention may assume. In these drawings Figure 1 is a perspective showing one of these illustrative embodiments of my invention Figure 2 is a view similar to Figure 1 showing a second illustrative embodiment of my invention,

Figure 3 is a view similar to Figures 1 and 2 showing a third illustrative embodiment of my invention,

Figure 4 is a view similar to Figures 1 through 3 showing a fourth illustrative embodiment of my invention,

Figure 5 is a view showing a fifth illustrative embodiment of my invention with the parts separated, while Figure 6 is a view similar to 1 through 4 showing the embodiment o my invention shown separated in Figure 5.

The embodiment of my invention shown in Figure 1 comprises a receptacle 11, arranged to be inserted within the customary recess in the refrigerating unit of mechanical refri eration apparatus of the domestic t .pe, and to be there suitably supported for e formation of artificial ice therein under the action of the refrigerating unit, and a strip 12 bent upon itself and dividing the space within the receptacle 11 into a plurality of smaller ice cake which would otherwise be formed in the rece tacle 11 into a plurality of smaller.

blocks sac of a size suitable for table use, the strip 12 bei removable from the receptacle 11 to facilitate cleanindg of the recepto facilitate to some extent removal of the ice blocks, and the stri 12 being formed resilient to further faci itate removal of the ice blocks, and also to normally hold the strip 12 in position within the receptacle 11.

The embodiment of my invention shown in Figure 2 substitutes for the strip 12 a strip 13 comprising a longitudinal section 14 dividaces to divide the single large.

ing the space within the receptacle'll into a plurality of longitudinally extend' corridors, and a plurality of sections 15 ividing each of these corridors into a plurality of similar spaces, the strip 13 being also removable, resilient, and he (1 in position within the receptacle 11 by its own resiliency. The embodiment of my invention shown in Figure 3 substitutes for the strips 12 and 13 a strip 16 bent back and forth upon itself as shown to again divide the space within the receptacle 11 into a plurality of corridors, and to then sub-divi e each corridor into a lurality of smaller s aces, the stri 16 also ing removable, resi em, and he (I in the receptacle 11 by means of its own resiliency.

T ie embodiment of my invention shown in Figure 4 substitutes for the strip 16 of Figure 3 a stri 17 similar to the strip 16 but formed to divide the space within the receptacle 11 into only two corridors, and each of the corridors into a smaller number of small spaces, this strip being removable, resilient, and held in position in the receptacle 11 by its own resiliency.

The embodiment of my invention shown in Figures 5 and 6 comprises a pair of strips 18 and 19 similar to each other, each bent upon itself to cross the other strip at intervals, and each provided at each crossing with a cutawa 20 to receive the portion of the other strip un-cut-away at that crossing, to thus rmit the two strips 18 and 19 to be assem led into a grid 21 as shown in Figure 6, the grid 21 relacing the strips 12 and 13 and 16 and 17 0 Figures 1 through 4 to effectively divide into small spaces the large space otherwise obtaining within the receptacle 11, the grid 21 being removable from the receptacle 11, the strips 18 and 19 being resilient, and the grid 21 being held within the receptacle 11 by the resiliency of the strips 18 and 19.

From the above description it will be apparent to those skilled in the art that I have provided new and im roved means for forming, by the action of t e refrigerating unit of domestic mechanical refrigeration apparatus, ice blocks suitable for table use. At the same time it will also be apparent to those skilled in the art first that under certain circumstances it may be desirable to secure the strips or grids in position within the receptacles, and that this may be done in any suitable manner, as by soldering or welding, and sec- 0nd that under certain circumstances it may be desirable to secure together the various parts of a single strip or the various strips of a single grid, and that this can readily be done by any suitable means, as by soldering or welding.

For these and other reasons it will be obvious to those skilled in the art that the particular embodiments of my invention herein shown and described may be variously changed and modified without departing from the scope of my invention or sacrificing the advantages thereof, and it will therefore be understood that the disclosure herein is illustrative only and that my invention is not limited thereto.

I claim:

1. A receptacle for the production of frozen fluid in mechanical refrigerators consisting of a metal pan, and a removable partition within said pan, said partition structure consisting solely of a single sheet of metal bent to divide the space within said pan into a plurality of triangular compartments.

2. A receptacle for the production of frozen fluid in mechanical refrigerators consisting of a metal pan, and a removable partition within said pan, said partition being formed to separate the space within said pan into a plurality of compartments substantially triangular in shape.

In testimony whereof I hereunto affix my signature.
